Using petrol as a main source of energy, during the 20th century, has caused considerable amounts of damage among which are atmospheric pollution and global warming. At the same time, many geologists and economists expect that the discovery rate of new pet ...
Electrochem. oxidn. of orgs. at thermally prepd. dimensionally stable metal oxide anodes (DSA) has been studied. In reactions involving only simple electron transfer, oxide electrodes exhibit an electrocatalytic activity similar to that of noble metal elec ...
Electrochemical acetoxylation has been widely investigated about 40 years ago. However, there are only a limited number of studies in non-aqueous electrolytes, mainly because of difficulties related with the extremely low electrical conductivity of organic ...
Among the numerous base metals tested for DSA type electrodes (e.g., titanium and its alloys, zirconium, niobium etc.), tantalum is a potentially excellent substrate owing to its good elec. cond. and corrosion resistance, and the favorable dielec. properti ...
The electrochem. oxidn. (or combustion) of orgs. with simultaneous oxygen evolution has been investigated using different oxide electrodes. A simplified mechanism for the electrochem. oxidn. of orgs. is presented, according to which selective oxidn. occurs ...
This paper describes the anodic oxidn. of various aliph. alcs. in pure water using a Nafion cation exchange membrane as a solid polymer electrolyte. The oxidn. was carried out on an IrO2 anode under conditions of simultaneous O2 evolution. The exptl. resul ...
Aluminum is produced by the electrolytic reduction of alumina dissolved in molten cryolite. This process requires carbon anodes which are consumed during the electrolysis. The anodes contribute roughly with 15% to the total aluminum production cost. If the ...
This paper concerns an evaluation of ozone (O-3) and planetary boundary layer (PBL) dynamics over the complex topography of the Grenoble region through a combination of measurements and mesoscale model (METPHOMOD) predictions for three days, during July 19 ...
A new parameter, the normalized current efficiency for the electro-combustion has been considered. This parameter allows to eliminate the mass transfer inefficiency and then can be defined as the ability of the anode to promote the electro-oxidn. and to re ...
Ozone prodn. in 5M H2SO4 with Ti/IrO2/SnO2 - Sb2O5 electrodes was studied. Electrodes were prepd. at 550 Deg by spray pyrolysis of a soln. of precursors contg. tin and antimony chlorides. The aim of this work was to elucidate the mechanism of activation an ...
